Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method) - Inductively coupled plasma and atomic absorption spectrometry methods LONG_TITLE A change to the Sequence1 Scope This part of ISO 21587 specifies inductively coupled plasma atomic emission (ICP AE) spectrometry and flame atomic absorption (FAA) spectrometry methods for the chemical analysis of aluminosilicate refractory products and raw materials. The methods are applicable to the determination of the following: silicon(IV) oxide (SiO2) aluminium oxide (Al2O3) iron(III) oxide (total iron oxide calculated as Fe2O3) titanium(IV) oxide (TiO2) manganese(II)
